Abstract

The strategic issue for rare metals manufacturers is availability of the own raw material base. Previously unused resources which include the lignites located at central watershed of the Yenisei river are becoming important due to depletion of traditional sources of raw materials. The comprehensive approach to the processing of the lignite which ensures the formation of sublimates germanium-enriched to 1,8 wt.% and ash rare earth metals-enriched to 1,2 wt.% was proposed. The regularities of rare earth metals leaching from ash residue with obtaining rich solutions suitable for further processing using selective sorbents have been studied
